Import Cryogenic Pump Seal — Buy in wholesale FOB from Supplier in India

The MB1-GAS cryogenic pump seal from Hydro-Serve Technologies is a non-contacting gas seal designed for use in liquid cryogenic gases under industrial conditions. It operates with a metallic bellows construction that eliminates the need for dynamic O-rings, reducing failure points. Shaft diameters range from 18 to 100 mm, with pressure tolerance up to 15 bars and temperatures from -196 °C to ambient. Rotational speeds are rated up to 10,000 rpm, making it suitable for high-speed centrifugal pumps handling liquefied natural gas, liquid oxygen, and liquid nitrogen.

Seal faces are manufactured from carbon, silicon carbide, or tungsten carbide, chosen for hardness and thermal stability in cryogenic environments. Secondary seals use FFKM, FKM, or HNBR elastomers, selected for chemical resistance and low-temperature flexibility. Metal components are made from SS-316, Hastelloy C, or Inconel 718, ensuring corrosion resistance and structural integrity under thermal cycling. These material combinations follow standard industry practices for cryogenic sealing, where thermal contraction and embrittlement are critical design factors.

This seal is primarily purchased by industrial gas producers, LNG terminals, and chemical processing plants that require reliable sealing in liquefied gas transfer systems. Buyers typically require certification of material traceability and pressure testing data. Packaging is standard industrial crate with desiccant, and lead time is confirmed upon order. Incoterms are typically FOB Mumbai, with payment terms negotiated per contract.

Hydro-Serve Technologies is based in Mumbai, India, with its registered address at 6, Zorastrian Compound, Adarsh Nagar, New Link Road, Jogeshwari (West). The company specializes in custom-engineered sealing solutions for cryogenic and high-pressure industrial applications. Its trust tier is classified as harbor, indicating verified business registration and contactability. There is no public data on years in operation, workforce size, or revenue figures.

The supplier does not claim certifications such as ISO 9001 or ASME, nor does it list client names or export volumes.
